I bought it used and it came with 2 Cascade Canister Filters, 3 AquaClear 110s, a UV sterilizer, a powerhead, an ocean clear canister filter made by red sea, and I have a spare Penguin Bio-Wheel 200. I was thinking maybe I keep the 2 Cascades and one AquaClear and sell the rest. But I'm not familiar with canisters or aqua clears so I need some input. What do you guys think I should go with?????
